change resource pool size if necessary, the value is under manifest section resource_pools.infrastructure.size

When everything is done, fire bosh deploy to deploy echo service into Cloud Foundry.

Deploy echo service under ccng v2

Deploying echo service under ccng is the same as that under legacy CC.
The difference is that to make echo service available, some additional
steps are necessary. To achieve that, you should use the high version
vmc and the vmc admin plugin:

$ADMIN_USER and $ADMIN_PASSWORD could be found in your bosh deployment
manifest under section uaa.scim.users. It may take several minutes
before it takes effect. Issue vmc info --services to make sure that
echo service is available.

The value of token argument, here is changeechotoken, must be same
with the value under manifest section properties.echo_gateway.token.
